Description
BHO retaining rings are axially assembled internal circlips with a bowed profile and are part of Rotor Clip’s tapered section retaining ring family. Installed into a groove in a housing/bore, the bowed design applies a preload to compensate for accumulated tolerances and maintain internal axial retention over the specified range.
